The excavator ... I think I made it after a volvo model and I tried not to use the CITY technics for the arm,because it's so unrealistic,but from Technic parts it is a little ugly,maybe I'll change that.

The container truck,I found an image of a random container truck and this came out but I think it looks grate ! Don't you think ?!?
Maybe it would be a little bit better if I'd change the arms with system parts and ad more details... What ever,it is good this way.
